## Use an element argument to prove each statement in 28-38. Assume that all sets are subsets of a universal set U.For all a sets A and B, if A ⊆ B then A ∩ B e = ∅ .

To determine

To Prove:

For all sets A and B, if AB then ABc=. ABc=

### Explanation of Solution

Given information:

The objective is to show that ABc=, for all the sets A and B using element method.

Concept used:

:Union of sets:Intersection of sets

: subset of set

: Null set

Calculation:

The objective is to show that ABc=, for all the sets A and B using element method.

Here, A and B are the subsets of universal set.

Let A and B be two sets such that AB.

Use the element method to prove the result
